Abstract

An expression is derived for the output signal of a reflecting acoustic microscope in scanning of a spherical object. It is shown that the character of the image of such an object depends significantly on the position of the focal plane relative to the center of curvature of the sphere. The experimental results are in good agreement with the theory.
